Meanwhile, Hamid et al. progressively increased the replacement of fine aggregate with quarry dust above 50% to understand its behaviour when used in concrete production [14]. The result from this study shows that the produced concrete with quarry dust above 50% yield a negative effect in workability and strength properties of concrete [14].
Dec 23, 2019· Ceramic waste is hard and durable.Ceramic waste can be used as a partial replacement of cement or as a partial replacement of fine aggregate sand as a supplementary addition to achieve different properties of concrete [3]. Properties of Ceramic Powder:-Inorganic. Highly resistant to chemical and biological forces
